Illustrative Biological Activity

Presented herein are 5-substituted-2-aminopyrimidine compounds whichselectively modulate, regulate, and/or inhibit signal transductionmediated by certain native and/or mutant tyrosine kinases implicated ina variety of human and animal diseases such as cell proliferative,metabolic, allergic, and degenerative disorders. By way of example only,these compounds are potent and selective c-kit inhibitors.

c-Kit Receptor

Mast cells are tissue elements derived from a particular subset ofhematopoietic stem cells that express CD34, c-kit and CD13 antigens.Mast cells are characterized by their heterogeneity, not only regardingtissue location and structure but also at the functional andhistochemical levels. Immature mast cell progenitors circulate in thebloodstream and differentiate into various tissues. Thesedifferentiation and proliferation processes are under the influence ofcytokines, one of utmost importance being Stem Cell Factor (SCF), alsotermed Kit ligand, Steel factor or Mast Cell Growth Factor. The StemCell Factor receptor is encoded by the protooncogene, c-kit, which isexpressed in hematopoietic progenitor cells, mast cells, germ cells,interstitial cells of Cajal (ICC), and some human tumors, and is alsoexpressed by non hematopoietic cells.

Tyrosine kinases are receptor type or non-receptor type proteins, whichtransfer the terminal phosphate of ATP to tyrosine residues of proteinsthereby activating or inactivating signal transduction pathways. TheStem Cell Factor receptor, c-kit, is a Type III transmembrane receptorprotein tyrosine kinase which initiates cell growth and proliferationsignal transduction cascades in response to SCF binding. Ligation ofc-kit receptor by SCF induces its dimerization followed by itstransphorilation, leading to the recruitment and activation of variousintracytoplasmic substrates. These activated substrates induce multipleintracellular signaling pathways responsible for cell proliferation andactivation. These proteins are known to be involved in many cellularmechanisms, which in case of disruption, lead to disorders such asabnormal cell proliferation and migration, as well as inflammation.

The activity of the c-kit receptor protein tyrosine kinase is regulatedin normal cells, and the normal functional activity of the c-kit geneproduct is essential for maintenance of normal hematopoeisis,melanogenesis, genetogensis, and growth and differentiation of mastcells. In addition to its importance in normal cellular physiologicactivities, c-kit plays a role in the biological aspects of certainhuman cancers, and unregulated c-kit kinase activity is implicated inthe pathogenesis of human cancers, and in certain tumors types.Proliferation of tumor cell growth mediated by c-kit can occur by aspecific mutation of the c-kit polypeptide that results in ligandindependent activation or by autocrine stimulation of the receptor. Inthe former case, mutations that cause constitutive activation of c-kitkinase activity in the absence of SCF binding are implicated inmalignant human cancers, including germ cell tumors, mast cell tumors,gastrointestinal stromal tumors, small-cell lung cancer, melanoma,breast cancer, acute myelogenous leukemia, neuroblastoma andmastocytosis.

Mast cells present in tissues of patients are implicated in orcontribute to the genesis of diseases such as autoimmune diseases(multiple sclerosis, rheumatoid arthritis, inflammatory bowel diseases(IBD)) allergic diseases (allergic sinusitis, allergic rhinitis andasthma), tumor angiogenesis, inflammatory diseases, and interstitialcystitis. In these diseases, mast cells participate in the destructionof tissues by releasing a cocktail of different proteases and mediatorssuch as histamine, neutral proteases, lipid-derived mediators(prostaglandins, thromboxanes and leucotrienes), and various cytokines(IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, TNF-α, GM-CSF, MIP-LA,MIP-lb, MIP-2 and IFN-γ).

Human are more and more afflicted in modern societies with allergicdisorders such as allergic sinusitis, allergic rhinitis and asthma. Forexample, in the USA alone, it is estimated that more than 87 millionpeople are coping with some form of allergic diseases. The financialburden of the treatments rises to a total of several billion dollars andis due to the recurrence of these diseases. Among these allergicdiseases, we can cite allergic rhinitis, allergic sinusitis,anaphylactic syndrome, urticaria, angioedema, atopic dermatitis,allergic contact dermatitis, erythema nodosum, erythema multiforme,cutaneous necrotizing venulitis and insect bite skin inflammation, butbronchial asthma is the most prevalent and recurrent disease severelyafflicting the human population.

Asthma is characterized by airflow obstruction, bronchialhyperresponsiveness and airway inflammation. Airway inflammation is themajor factor in the development and perpetuation of asthma. In allergicasthma, which is the most frequent, especially in children, and betterstudied form of the disease, allergens are thought to initiate theinflammatory process by inducing a T-lymphocyte mediated response (TH2)that results in the production of allergen-specific IgE. IgE bind to itshigh-affinity receptor FCERI on pulmonary mast cells triggering a type I(IgE-mediated) immediate allergic response.

Mast cell activation induces diverse effector responses, such assecretion of allergic mediators, proteases, chemokines such as MCP-1 andRANTES, leukotrienes, prostaglandins, neurotrophins, induction ofcytokine gene transcription (IL-4, IL-5, IL-6, IL-13, TNFA and GM-CSF).These mediators contribute to creating the asthmatic phenotype by theireffects on endothelial cells, smooth muscle cells and fibroblasts and onextracellular matrix, and by recruiting other inflammatory cells.

Different treatments are available to alleviate the symptoms associatedwith allergic diseases. For instance, treatments for severe allergicdiseases such as asthma, include combination of histamine H₁-receptorantagonists with antagonists of leukotriene receptors or 5-lipoxygenaseinhibitors. However, anti-histamine compounds have been found to be lesseffective and do not provide a solution to the recurrence of asthma, andthe latter treatment only reduces inflammation symptoms associated withallergic diseases and cannot be considered as a cure on the long run. Inresponse to this problem, interleukin-2 (IL-2) has been used to suppressallergic disorders, but the induction of death by apoptosis of asubpopulation of T lymphocytes has many side effects limiting suchtherapy to the most severe forms of allergic diseases.

Mast cells may play a role in asthma as suggested by the humanizedanti-IgE monoclonal antibody treatment. The rationale of anti-IgEtherapy is to specifically target IgE with the result of inactivatingfree anti-IgE and halting further IgE production. In addition, since IgElevels are a major regulator of the level of expression of IgE receptorFceRI, one aim of this therapy is to decrease FceRI expression on mastcells and basophils, and, as a consequence, to decrease the capacity ofthese cells to be activated. The capacity of the anti-IgE therapy todecrease FceRI expression has been demonstrated on basophils. Thedecrease in FceRI expression on basophils is associated with a decreasein the capacity of basophils to secrete mediators upon activation. Eventhough the effect of the anti-IgE therapy on pilmonary mast cells hasnot been studied because these cells are difficult to harvest. Thesetrials have shown that the anti-IgE therapy is capable of improving someof the parameters of asthma, for example corticosteroid usage.Nevertheless, antibody based therapy is not suitable to repeatedtreatment of the most recurrent forms of allergic diseases. In addition,compositions comprising tryptase inhibitors for treating mast-cellmediated conditions are may be used, but decreasing the activity of freetryptase released by activated mast cells is not sufficient to blockchain reactions caused by the others mast cells released factors.Therefore, there is a need for alternative treatments of allergicdiseases and/or conditions which would be more effective on the longterm and would be well tolerated, especially in respect to repeatedadministration.

Non-insulin-dependent diabetes mellitus (NLDDM), also known as type IIdiabetes, is defined as a chronic disease appearing when insulin isinefficient in promoting glucose uptake by cells, resulting in increasedlevels of glucose in the blood. This disease affects about 100 millionpeople world-wide, 75% of which are obese at the time of diagnosis.

Diminution in the ability of the cells to respond adequately to insulinis often referred as insulin resistance. Excessive weight and lack ofphysical activity are regarded as being responsible for inducing insulinresistance. Over many years, the failure of the glucose uptakeregulation leads to the development of Type II diabetes and the bloodglucose level needs to be regulated with medicinal products. Ultimately,unregulated blood glucose level is responsible for blood vessels, kidneyand eye damages, as well as cardiovascular diseases. This tissue damagescontribute to mortality in diabetics.

Hypoglycemic agents such as sulfonylureas work by triggering thepancreas to make more insulin, which lower blood glucose. The sideeffects of sulfonylureas include hypoglycemia, renal and hepaticdisease, gastrointestinal disturbances, increased cardiovascularmortality, dermatological reactions, drowsiness and headache. Biguanideslower blood glucose levels by reducing intestinal glucose absorption andhepatic glucose, but not by stimulating insulin secretion. The majorside effects of biguanidine are lactic acidosis and increasedcardiovascular mortality. Alpha-glucosidase inhibitors decrease theabsorption of carbohydrates from the digestive tract, thereby loweringthe after-meal glucose level, but gastrointestinal side effects andhypoglycemia are observed. Thiazolidinediones, such as rosiglitazone arePPARgamma agonists and increase the cell's sensitivity to insulin.However, they may be responsible for water retention, liver diseases,cardiovascular diseases, red blood cell abnormalities, and headache.

Because treatment of Type II diabetes requires long term administrationof compounds lowering blood glucose level, there is still a great needfor improved and safer methods. C-kit inhibitors may also be used in thetreatment of type II diabetes. Inhibition of c-kit activity reducescellular proliferation, depleting the mast cells responsible fordiseases and/or conditions, such as allergic diseases, therebysuggesting a role for use of inhibitors of c-kit in the treatment ofc-kit dependent diseases and/or conditions, such as diabetes. Describedherein are diarylamine compounds, pharmaceutical compositions andmedicaments, which include such diarylamine compounds or apharmaceutically acceptable salt or solvate thereof, that are potent andselective c-kit inhibitors and which selectively modulate, regulate,and/or inhibit signal transduction mediated by certain native and/ormutant tyrosine kinases implicated in a variety of human and animaldiseases such as, by way of example only, diabetes.

Neurons propagate a signal in the form of an action potential along itsaxon to other neurons or to effector cells. Many positive or negativesignals are exchanged between neurons and are integrated to producemeaningful firing patterns. The communication between two neurons isbased on the action of numerous neurotransmitters on specific receptorslocated at the synapses. A disruption in the regulation ofneurotransmission is responsible for neurologic and psychiatricdiseases. Furthermore, the activity of neurotransmitters on theirrespective receptor is normally time limited so that receptors canrespond repeatedly to the next waves of stimuli. In this regard,different mechanisms abolish the action of neurotransmitters, forinstance they can be pumped back into the presynaptic nerve terminals byactive processes (reuptake), they can be destroyed by enzymes, or theysimply diffuse into the surrounding area.

Changes in neurotransmitter synthesis, storage, release, or degradationor changes in the number and affinity of receptors can affectneurotransmission and cause clinical disorders. Among neurotransmitters,glutamate and aspartate are the major excitatory neurotransmitters,whereas aminobutyric acid (GABA) is the major inhibitoryneurotransmitter in the brain. The first theory about depressionconcerned the noradrenergic system (NS) (Shildkraut J. et al. 1965, AmJ. Psychiat. 12: 509-522). At that time, it was observed that tricycliccompounds (ADT) and monoamine-oxidase inhibitors modified the level ofnoradrenaline. Later on, in 1978, Sulser F. et al., Biochem Pharmacol.27: 257-261 showed that these antidepressants lead to a decrease in thenumber of post-synaptic (3-Adrenergis receptors. Therefore, it wasthought that depression was due to the deregulation of the noradrenergicpre-synaptic stimuli as well as the post-synaptic receptors (Siever L J.et AL. (1985), Am. J. Psychiat. 142, 1017-1031).

In 1986, Rasmussen et al., Brain Res. 385: 395-400 demonstrated thepresence of serotonin (5-hydroxytriptamin, 5-HT) receptors in NAneurones. Treatments with ADT were shown to provoke also adown-regulation of the 5-HT₂ receptors in Sugrue M. F. et al, 1981,Pharmacol. Ther. 13: 219-247. As a consequence, it appears that the NAand 5-HT systems play a crucial role in the regulation of mood andbehaviour. In the nineties, research has focused on the finding ofspecific serotonin re-uptake inhibitors (SSRI), such as fluoxetin,parxetin or sertralin (Pinder R. M. et al., 1993, Med. Res. Rev. 13:259-325). Serotonin (5-hydroxytryptamine, or 5-HT) levels are controlledby the uptake of tryptophan and intraneuronal monoamine oxidaseactivity. In the meantime, a decrease in the level of HVA, the maincatabolic of dopamin (DA), was observed in depressed patients (Kapur S.et al., 1992, Biol. Psychiat. 32: 1-17). GABA was also shown to beinvolved in the physiopathology of depression since (i) unpolar patientsdisplay decreased level of GABA, (ii) some antidepressants induce therelease of GABA in vivo and (iii) agonists of GABA receptors haveantidepressant effects (Lloyd K. G. et al., 1989, Prog.Neuro-Psycopharmacol. Biol. Psychiat. 13: 341-351).

More recently, it has been reported that other factors may be involvedin CNS disorders. For example, it has been observed from 30 to 70% ofpatients afflicted with melancholia have high level of plasmaticcortisol and escape to the test with dexamethasone described in CarollB. J. et al., 1981, Arch. Gen. Psychiat. 38: 15. In addition,cortocosteroids modify (i) the expression of serotoninergic receptorsand (ii) the activity of tryptophan hydroxylase, which is the key enzymein the synthesis of 5-HT (Biegon A., 1990, Ann. NY Acad. Sci. 600:427-431).

Regarding post-partum or post-menopause depression, repeatedadministration of oestrogene induces a down-regulation of dopaminergicD₂ receptors (Munemura M. et al., 1989, Endocrinology 124: 346-355 andRoy E. J. et al., 1990, Brain. Res. Bull. 25: 221-227).

Other neurotransmitters include the well known acetylcholine,norepinephrine which interacts with adrenergic receptors and which isregulated by tyrosine hydroxylase and monoamine oxidase, endorphinswhich are polypeptides that activate many central neurons and interactwith opioid receptors, enkephalins, dynorphins, histamine, vasopressin,vasoactive intestinal peptide, carnosine, bradykinin, cholecystokinin,bombesin, somatostatin, corticotropin releasing factor, neurotensin, andadenosine.

As mentioned above, any imbalance in these neurotransmitters or anyderegulation of associated receptors may lead to the development of CNSdisorders ranging from psychiatric diseases to migraine, pain, memoryloss and nerve cells degeneracy.

As of today, available treatments include selective serotonin reuptakeinhibitors (SSRIS) such as fluoxetine, sertraline, paroxetine, andfluvoxamine. Other compounds include nefaxodone which blocks the 5-HT₂receptor and inhibits reuptake of 5-HT and norepinephrine, trazodonewhich is a 5-HT₂ receptor blocker and a 1-noradrenergic blocker,mirtazapine which blocks 2-adrenergic autoreceptors as well as 5-HT₂,5-HT₃ and HI receptors, tricyclic compounds such as imipramine anddesipramine, tetracyclic compounds which increase the level of freenorepinephrine and of 5-HT, and monoamine oxidase inhibitors (MAOI)which inhibit the oxidative deamination of norepinephrine, dopamine, and5-HT. We can also cite lithium-antidepressants for treating bipolardisorder.

However, the above mentioned compounds display numerous side effectssuch as tachycardia, sedation and weight gain. In addition, thesecompounds are only effective in about 65% of depressed patients, whichimplies a large population afflicted with the so-called “refractorydepression”. In some cases, the life of patients is in jeopardy at theextent that hospitalization and electroconvulsive therapy is required,thus showing the seriousness of these diseases.

Schizophrenia is also a serious mental disorder affecting about 1% ofwestern countries population. Antipsychotic (neuroleptic) drugsavailable include chlorpromazine and haloperidol which show affinity forthe dopamine 2 receptor. But, adverse side effects such as sedation,dystonia, tremors and akathisia have been commonly observed and asignificant percentage of patients do not respond to the treatments.

Therefore, the problem is to find alternative solutions to provide arelief and a cure for the numerous patients afflicted with thesediseases. The activation of mast cells by different stimuli such asstress, trauma, infection as well as neurotransmitters, may participatein the exacerbation of the chemical imbalance causing CNS disorders.More specifically, mast cell degranulation is stimulated by commonneurotransmitters such as neurotensin, somatostatin, substance P andacetylcholine, by growth or survival factors, notably NGF, TGFfβL Mastcells involved in the response to such stimulus can be brain mast cellsbut also other mast cells releasing the content of their granules in theblood stream that ultimately reach sensory, motor or brain neurons.Brain mast cells staining is CTMC staining-like but they show thesecretory pattern of MMC, implying that they constitute a particularsubset of mast cells presenting specificities.

Following mast cells activation, released granules liberate variousfactors capable of modulating and altering neurotransmission and neuronssurvival. Among such factors, serotonin is important since an increaseof the level of free serotonin has been observed in depressed patients.Alternatively, the sudden burst of serotonin may be followed by a periodof serotonin shortage, leading to pain and migraine. As a consequence,it is believed that mast cells exacerbate in autocrine or paracrinemanner the deregulation of neurotransmission. For example, anxiety orstress-induced release of neurotransmitters such as serotonin activatesmast cells, which in turn release the content of their granules, furthercontributing to the chemical imbalance in the brain leading to CNSdisorders.

Other mediators released by mast cells can be categorized intovasoactive, nociceptive, proinflammatory and other neurotransmitters.Taken together, these factors are able to induce great disturbance inthe activity of neurons, whether they are sensory, motor, or CNSneurons.

In addition, patients afflicted with mastocytosis are more incline todevelop CNS disorders than the normal population. This can be explainedby the presence of activating mutations in the c-kit receptor, whichinduce degranulation of mast cells and a burst of factors contributingto chemical imbalance and neurotransmission alteration.

In some cases, activated mast cells can also participate in thedestruction of neuronal tissues by releasing a cocktail of differentproteases and mediators categorized into three groups: preformedgranule-associated mediators (histamine, proteoglycans, and neutralproteases), lipid-derived mediators (prostaglandins, thromboxanes andleucotrienes), and various cytokines (IL-1, IL-2, IL-3, IL-4, IL-5,IL-6, IL-8, TNF-A, GM-CSF, MIP-LA, MIP-lb, MIP-2 and IFN-y). Theliberation by activated mast cells of mediators (TNF-A, histamine,leukotrienes, prostaglandines etc.) as well as proteases may i) induceinflammation and vasodilatation and ii) participate in the neuronaltissue destruction process.

Inhibition of c-kit activity reduces cellular proliferation, depletingthe mast cells responsible for diseases and/or conditions, such asallergic diseases, thereby suggesting a role for use of inhibitors ofc-kit in the treatment of c-kit dependent diseases and/or conditions,such as CNS disorders. Described herein are diarylamine compounds,pharmaceutical compositions and medicaments, which include suchdiarylamine compounds or a pharmaceutically acceptable salt or solvatethereof, that are potent and selective c-kit inhibitors and whichselectively modulate, regulate, and/or inhibit signal transductionmediated by certain native and/or mutant tyrosine kinases implicated ina variety of human and animal diseases such as, by way of example only,CNS disorders.

Drug dependence is the result of a phenomenon called tolerance, which isthe need to increase the dose of the drug to maintain its full effect,and of physical dependence, which is the habituation of the body to adrug. When the intake of a drug is discontinued, individual mayexperience unpleasant withdrawal syndrome. This syndrome is difficult toqualify or quantify but it can be illustrated by a strong feeling ofunmet satisfaction.

This episode has been described by former drug addicted individuals as“a strong scream and complaint emanating from the body”, which indicatesthe seriousness and the difficulties encountered by these individuals.In addition, it must be emphasized that drug addiction is accompaniedwith or may follow psychiatric disorders such as anxiety, depression,and schizophrenia.

Drugs leading to dependence can be classified into two types. One typeis responsible for psychologic dependence such as cocaine, marijuana,amphetamine, and hallucinogens. The other type is more prone to physicaldependence, but one must not rule out psychologic dependence, and isexemplified by drugs such as heroin, alcohol and nicotine.

Of course, any drug that acts on the CNS may involve a risk ofdependence. For example, one of the side effects of benzodiazepinederivatives is dependence. In animal models, it has been observed thatadministration of drugs such as opioids, cocaine, amphetamine, nicotine,and benzodiazepines is associated with enhanced dopaminergictransmission. The problem is that the increased level of DA may befollowed by a down regulation of DA receptors. This might explain inpart the observed withdrawal symptoms that are sometimes associated withdepression, mood disorders, insomnia and other unwanted dependencedisorders.

Drug addiction may be responsible for, or arise from, job pressure orfamilial problems resulting in anxiety or depression. At the extreme ofthe spectrum, it can result in hospitalization for overdose, withdrawalepisodes and associated substance use disorders.

Finally, anxyolitics such as benzodiazepines are being consumed more andmore, therefore, it is urgent to find solutions for preventing andmanaging drug dependence and withdrawal symptoms. The socioeconomicconsequences of reliable solutions will have a huge impact in modernsocieties since addiction is often accompanied not only withsusceptibility to HIV infection and hepatitis. Consequently, researchprograms aimed at developing compounds capable of alleviating drugdependence and withdrawal symptoms must be encouraged and considered asa top priority.

Substance abuse and drug addiction introduce changes in neurotransmittersynthesis, storage, release, or in the number and affinity of receptors.This can affect neurotransmission and cause drug dependence andwithdrawal symptoms. Among neurotransmitters, example include, but arenot limited to, glutamate and aspartate, which are the major excitatoryneurotransmitters, aminobutyric acid (GABA), which is the majorinhibitory neurotransmitter in the brain and shown to be involved in thephysiopathology of depression; serotinin (5-HT); dopamine (DA), whichwas observed in depressed patients; acetylcholine, norepinephrine whichinteracts with adrenergic receptors and which is regulated by tyrosinehydroxylase and monoamine oxidase; endorphins, which are polypeptidesthat activate many central neurons and interact with opioid receptors,and others neurotransmitters such as enkephalins, dynorphins, histamine,vasopressin, vasoactive intestinal peptide, carnosine, bradykinin,cholecystokinin, bombesin, somatostatin, corticotropin releasing factor,neurotensin, and adenosine. As mentioned above, any imbalance in theseneurotransmitters or any deregulation of associated receptors due todrug intake may lead to the development of drug dependence andwithdrawal symptoms.

It has been identified that mast cells are involved in or contribute todrug dependence and withdrawal symptoms. The activation of mast cells bydifferent drugs, including, but not limited to, salicylic derivatives,morphine derivatives, opioids, heroin, amphetamines, alcohol, nicotine,analgesics, anesthetics, and anxyolitics results in the degranulation ofmast cells, which participate in the exacerbation of the chemicalimbalance responsible for drug habituation and withdrawal syndrome. Inaddition, following mast cells activation, released granules liberatevarious factors capable of modulating and altering neurotransmission.Among such factors, is morphine which is bound or stored in mast cellsgranules. Also tobacco smoke induces the release of mediators fromcanine mast cells and modulates prostaglandin production leading toasthma. In addition, patients afflicted with mastocytosis are moreincline to develop substance use disorders than the normal population.This can be explained by the presence of activating mutations in thec-kit receptor, which induce degranulation of mast cells and a burst offactors contributing to chemical imbalance and neurotransmissionalteration.

Presently, there is no treatment providing relief and help toindividuals to withdraw from their addiction are available. C-kitinhibitors may be used for treating substance abuse disorders,particularly drug addiction, drug abuse, drug habituation, drugdependence, withdrawal syndrome and overdose, comprising administering acompound capable of depleting mast cells to a human in need of suchtreatment.

Inhibition of c-kit activity reduces cellular proliferation, depletingthe mast cells responsible for diseases and/or conditions, such as drugdependency, thereby suggesting a role for use of inhibitors of c-kit inthe treatment of c-kit dependent diseases and/or conditions, such asdrug dependency.

In the reactions described, it may be necessary to protect reactivefunctional groups, for example hydroxy, amino, imino, thio or carboxygroups, where these are desired in the final product, to avoid theirunwanted participation in the reactions. Protecting groups are used toblock some or all reactive moieties and prevent such groups fromparticipating in chemical reactions until the protective group isremoved. It is preferred that each protective group be removable by adifferent means. Protective groups that are cleaved under totallydisparate reaction conditions fulfill the requirement of differentialremoval. Protective groups can be removed by acid, base, andhydrogenolysis. Groups such as trityl, dimethoxytrityl, acetal andt-butyldimethylsilyl are acid labile and may be used to protect carboxyand hydroxy reactive moieties in the presence of amino groups protectedwith Cbz groups, which are removable by hydrogenolysis, and Fmoc groups,which are base labile. Carboxylic acid and hydroxy reactive moieties maybe blocked with base labile groups such as, but not limited to, methyl,ethyl, and acetyl in the presence of amines blocked with acid labilegroups such as t-butyl carbamate or with carbamates that are both acidand base stable but hydrolytically removable.

Carboxylic acid and hydroxy reactive moieties may also be blocked withhydrolytically removable protective groups such as the benzyl group,while amine groups capable of hydrogen bonding with acids may be blockedwith base labile groups such as Fmoc. Carboxylic acid reactive moietiesmay be protected by conversion to simple ester compounds as exemplifiedherein, or they may be blocked with oxidatively-removable protectivegroups such as 2,4-dimethoxybenzyl, while co-existing amino groups maybe blocked with fluoride labile silyl carbamates.

Allyl blocking groups are useful in then presence of acid- andbase-protecting groups since the former are stable and can besubsequently removed by metal or pi-acid catalysts. For example, anallyl-blocked carboxylic acid can be deprotected with a Pd₀-catalyzedreaction in the presence of acid labile t-butyl carbamate or base-labileacetate amine protecting groups. Yet another form of protecting group isa resin to which a compound or intermediate may be attached. As long asthe residue is attached to the resin, that functional group is blockedand cannot react. Once released from the resin, the functional group isavailable to react.

Typically blocking/protecting groups may be selected from:

Other protecting groups, plus a detailed description of techniquesapplicable to the creation of protecting groups and their removal aredescribed in Greene and Wuts, Protective Groups in Organic Synthesis,3rd Ed., John Wiley & Sons, New York, N.Y., 1999, and Kocienski,Protective Groups, Thieme Verlag, New York, N.Y., 1994, which areincorporated herein by reference in their entirety.

Alternatively, compounds of Formula (A) or Formula (B) can be preparedas a pharmaceutically acceptable base addition salts (which is a type ofa pharmaceutically acceptable salt) by reacting the free acid form ofthe compound with a pharmaceutically acceptable inorganic or organicbase, including, but not limited to organic bases such as ethanolamine,diethanolamine, triethanolamine, tromethamine, N-methylglucamine, andthe like and inorganic bases such as aluminum hydroxide, calciumhydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, andthe like.

It should be understood that a reference to a pharmaceuticallyacceptable salt includes the solvent addition forms or crystal formsthereof, particularly solvates or polymorphs. Solvates contain eitherstoichiometric or non-stoichiometric amounts of a solvent, and may beformed during the process of crystallization with pharmaceuticallyacceptable solvents such as water, ethanol, and the like. Hydrates areformed when the solvent is water, or alcoholates are formed when thesolvent is alcohol. Solvates of compounds of Formula (A) or Formula (B)can be conveniently prepared or formed during the processes describedherein. By way of example only, hydrates of compounds of Formula (A) orFormula (B) can be conveniently prepared by recrystallization from anaqueous/organic solvent mixture, using organic solvents including, butnot limited to, dioxane, tetrahydrofuran or methanol. In addition, thecompounds provided herein can exist in unsolvated as well as solvatedforms. In general, the solvated forms are considered equivalent to theunsolvated forms for the purposes of the compounds and methods providedherein.

Compounds of Formula (A) or Formula (B) include crystalline forms, alsoknown as polymorphs. Polymorphs include the different crystal packingarrangements of the same elemental composition of a compound. Polymorphsusually have different X-ray diffraction patterns, infrared spectra,melting points, density, hardness, crystal shape, optical and electricalproperties, stability, and solubility. Various factors such as therecrystallization solvent, rate of crystallization, and storagetemperature may cause a single crystal form to dominate.

Compounds of Formula (A) or Formula (B) in unoxidized form can beprepared from N-oxides of compounds of Formula (A) or Formula (B) bytreating with a reducing agent, such as, but not limited to, sulfur,sulfur dioxide, triphenyl phosphine, lithium borohydride, sodiumborohydride, phosphorus trichloride, tribromide, or the like in asuitable inert organic solvent, such as, but not limited to,acetonitrile, ethanol, aqueous dioxane, or the like at 0 to 80° C.

Compounds of Formula (A) or Formula (B) can be prepared as prodrugs.Prodrugs are generally drug precursors that, following administration toa subject and subsequent absorption, are converted to an active, or amore active species via some process, such as conversion by a metabolicpathway. Some prodrugs have a chemical group present on the prodrug thatrenders it less active and/or confers solubility or some other propertyto the drug. Once the chemical group has been cleaved and/or modifiedfrom the prodrug the active drug is generated. Prodrugs are often usefulbecause, in some situations, they may be easier to administer than theparent drug. They may, for instance, be bioavailable by oraladministration whereas the parent is not. The prodrug may also haveimproved solubility in pharmaceutical compositions over the parent drug.An example, without limitation, of a prodrug would be a compound ofFormula (A) or Formula (B) which is administered as an ester (the“prodrug”) to facilitate transmittal across a cell membrane where watersolubility is detrimental to mobility but which then is metabolicallyhydrolyzed to the carboxylic acid, the active entity, once inside thecell where water-solubility is beneficial. A further example of aprodrug might be a short peptide (polyaminoacid) bonded to an acid groupwhere the peptide is metabolized to reveal the active moiety.

Prodrugs may be designed as reversible drug derivatives, for use asmodifiers to enhance drug transport to site-specific tissues. The designof prodrugs to date has been to increase the effective water solubilityof the therapeutic compound for targeting to regions where water is theprincipal solvent.

Roche,Bioreversible Carriers in Drug Design, American PharmaceuticalAssociation and Pergamon Press, 1987, all incorporated herein in theirentirety.

Additionally, prodrug derivatives of compounds of Formula (A) or Formula(B) can be prepared by methods known to those of ordinary skill in theart (e.g., for further details see Saulnier et al., (1994), Bioorganicand Medicinal Chemistry Letters, Vol. 4, p. 1985). By way of exampleonly, appropriate prodrugs can be prepared by reacting a non-derivatizedcompound of Formula (A) or Formula (B) with a suitable carbamylatingagent, such as, but not limited to, 1,1-acyloxyalkylcarbanochloridate,para-nitrophenyl carbonate, or the like. Prodrug forms of the hereindescribed compounds, wherein the prodrug is metabolized in vivo toproduce a derivative as set forth herein are included within the scopeof the claims. Indeed, some of the herein-described compounds may be aprodrug for another derivative or active compound.

Sites on the aromatic ring portion of compounds of Formula (A) orFormula (B) can be susceptible to various metabolic reactions, thereforeincorporation of appropriate substituents on the aromatic ringstructures, such as, by way of example only, halogens can reduce,minimize or eliminate this metabolic pathway.

Compounds of Formula (A) or Formula (B) can be optically pureenantiomers or a racemic mixture. Compounds of Formula (A) or Formula(B) can be prepared as their individual stereoisomers by reacting aracemix mixture of the compound with an optically active resolving agentto form a pair of diastereoisomeric compounds, separating thediastereomers and recovering the optically pure enentiomers.

The compounds of Formula (A) or Formula (B)may possess one or more chiral centers and each center may exist in theR or S configuration. The compounds presented herein include alldiastereomeric, enantiomeric, and epimeric forms as well as theappropriate mixtures thereof. Compounds of Formula (A) or Formula (B)can be prepared as their individual stereoisomers by reacting a racemicmixture of the compound with an optically active resolving agent to forma pair of diastereoisomeric compounds, separating the diastereomers andrecovering the optically pure enantiomers. While resolution ofenantiomers can be carried out using covalent diastereomeric derivativesof the compounds described herein, dissociable complexes are preferred(e.g., crystalline diastereomeric salts). Diastereomers have distinctphysical properties (e.g., melting points, boiling points, solubilities,reactivity, etc.) and can be readily separated by taking advantage ofthese dissimilarities. The diastereomers can be separated by chiralchromatography, or preferably, by separation/resolution techniques basedupon differences in solubility. The optically pure enantiomer is thenrecovered, along with the resolving agent, by any practical means thatwould not result in racemization. A more detailed description of thetechniques applicable to the resolution of stereoisomers of compoundsfrom their racemic mixture can be found in Jean Jacques, Andre Collet,Samuel H.

The compounds of Formula (A) or Formula (B) can be used in thepreparation of medicaments for the treatment of diseases or conditionsin which c-kit receptor activity contributes to the pathology and/orsymptomology of the disease. In addition, a method for treating any ofthe diseases or conditions described herein in a subject in need of suchtreatment, involves administration of pharmaceutical compositionscontaining at least one compound of Formula (A) or Formula (B), or apharmaceutically acceptable salt, pharmaceutically acceptable N-oxide,pharmaceutically active metabolite, pharmaceutically acceptable prodrug,or pharmaceutically acceptable solvate thereof, in therapeuticallyeffective amounts to said subject

The compositions containing the compound(s) described herein can beadministered for prophylactic and/or therapeutic treatments. Intherapeutic applications, the compositions are administered to a patientalready suffering from a disease or condition, in an amount sufficientto cure or at least partially arrest the symptoms of the disease orcondition. Amounts effective for this use will depend on the severityand course of the disease or condition, previous therapy, the patient'shealth status, weight, and response to the drugs, and the judgment ofthe treating physician. It is considered well within the skill of theart for one to determine such therapeutically effective amounts byroutine experimentation (including, but not limited to, a doseescalation clinical trial).

In the case wherein the patient's condition does not improve, upon thedoctor's discretion the administration of the compounds may beadministered chronically, that is, for an extended period of time,including throughout the duration of the patient's life in order toameliorate or otherwise control or limit the symptoms of the patient'sdisease or condition. In the case wherein the patient's status doesimprove, upon the doctor's discretion the administration of thecompounds may be given continuously or temporarily suspended for acertain length of time (i.e., a “drug holiday”).

Once improvement of the patient's conditions has occurred, a maintenancedose is administered if necessary. Subsequently, the dosage or thefrequency of administration, or both, can be reduced, as a function ofthe symptoms, to a level at which the improved disease or condition isretained. Patients can, however, require intermittent treatment on along-term basis upon any recurrence of symptoms.

In certain instances, it may be appropriate to administertherapeutically effective amounts of at least one of the compoundsdescribed herein (or a pharmaceutically acceptable salts,pharmaceutically acceptable N-oxides, pharmaceutically activemetabolites, pharmaceutically acceptable prodrugs, and pharmaceuticallyacceptable solvates thereof) in combination with another therapeuticagent. By way of example only, if one of the side effects experienced bya patient upon receiving one of the compounds herein is inflammation,then it may be appropriate to administer an anti-inflammatory agent incombination with the initial therapeutic agent. Or, by way of exampleonly, the therapeutic effectiveness of one of the compounds describedherein may be enhanced by administration of an adjuvant (i.e., by itselfthe adjuvant may only have minimal therapeutic benefit, but incombination with another therapeutic agent, the overall therapeuticbenefit to the patient is enhanced). Or, by way of example only, thebenefit of experienced by a patient may be increased by administeringone of the compounds described herein with another therapeutic agent(which also includes a therapeutic regimen) that also has therapeuticbenefit. In any case, regardless of the disease or condition beingtreated, the overall benefit experienced by the patient may simply beadditive of the two therapeutic agents or the patient may experience asynergistic benefit. For example, synergistic effects can occur withcompounds of Formula (A) or Formula (B) and other substances used in thetreatment of neoplastic disease, allergy disease, inflammatory disease,autoimmume disease, graft-versus-host disease, metabolic syndrome, CNSrelated disorders, neurodegenerative disease, pain, substance abusedisorders, prion diseases, cancers, heart diseases, fibrotic diseases,idiopathic pulmonary arterial hypertension (IPAH), or primary pulmonaryhypertension (PPH). Examples of such bronchodilators, including, but notlimited to, β₂-agonists, methylxanthines and anticholinerigcs;anti-inflammatory agents, including, but not limited to, corticosteroidsand cromolyns, leukotriene antagonists, and IgE blockers, including butnot limited to, omalizumab, also known as xolair. Where the compoundsdescribed herein are administered in conjunction with other therapies,dosages of the co-administered compounds will of course vary dependingon the type of co-drug employed, on the specific drug employed, on thedisease or condition being treated and so forth. In addition, whenco-administered with one or more biologically active agents, thecompound provided herein may be administered either simultaneously withthe biologically active agent(s), or sequentially. If administeredsequentially, the attending physician will decide on the appropriatesequence of administering protein in combination with the biologicallyactive agent(s).

In any case, the multiple therapeutic agents (one of which is one of thecompounds described herein) may be administered in any order or evensimultaneously. If simultaneously, the multiple therapeutic agents maybe provided in a single, unified form, or in multiple forms (by way ofexample only, either as a single pill or as two separate pills). One ofthe therapeutic agents may be given in multiple doses, or both may begiven as multiple doses. If not simultaneous, the timing between themultiple doses may vary from more than zero weeks to less than fourweeks. In addition, the combination methods, compositions andformulations are not to be limited to the use of only two agents; weenvision the use of multiple therapeutic combinations.

In addition, the compounds of Formula (A) or Formula (B) may also beused in combination with procedures that may provide additional orsynergistic benefit to the patient. By way of example only, patients areexpected to find therapeutic and/or prophylactic benefit in the methodsdescribed herein, wherein pharmaceutical composition of Formula (A) orFormula (B) and/or combinations with other therapeutics are combinedwith genetic testing to determine whether that individual is a carrierof a mutant gene that is known to be correlated with certain diseases orconditions.

The compounds of Formula (A) or Formula (B) and combination therapiescan be administered before, during or after the occurrence of a diseaseor condition, and the timing of administering the composition containinga compound can vary. Thus, for example, the compounds can be used as aprophylactic and can be administered continuously to subjects with apropensity to conditions or diseases in order to prevent the occurrenceof the disease or condition. The compounds and compositions can beadministered to a subject during or as soon as possible after the onsetof the symptoms. The administration of the compounds can be initiatedwithin the first 48 hours of the onset of the symptoms, preferablywithin the first 48 hours of the onset of the symptoms, more preferablywithin the first 6 hours of the onset of the symptoms, and mostpreferably within 3 hours of the onset of the symptoms. The initialadministration can be via any route practical, such as, for example, anintravenous injection, a bolus injection, infusion over 5 minutes toabout 5 hours, a pill, a capsule, transdermal patch, buccal delivery,and the like, or combination thereof. A compound is preferablyadministered as soon as is practicable after the onset of a disease orcondition is detected or suspected, and for a length of time necessaryfor the treatment of the disease, such as, for example, from about 1month to about 3 months. The length of treatment can vary for eachsubject, and the length can be determined using the known criteria. Forexample, the compound or a formulation containing the compound can beadministered for at least 2 weeks, preferably about 1 month to about 5years, and more preferably from about 1 month to about 3 years.

The pharmaceutical composition described herein may be in unit dosageforms suitable for single administration of precise dosages. In unitdosage form, the formulation is divided into unit doses containingappropriate quantities of one or more compound. The unit dosage may bein the form of a package containing discrete quantities of theformulation. Non-limiting examples are packaged tablets or capsules, andpowders in vials or ampoules. Aqueous suspension compositions can bepackaged in single-dose non-reclosable containers. Alternatively,multiple-dose reclosable containers can be used, in which case it istypical to include a preservative in the composition. By way of exampleonly, formulations for parenteral injection may be presented in unitdosage form, which include, but are not limited to ampoules, or inmulti-dose containers, with an added preservative.

The daily dosages appropriate for the compounds of Formula (A) orFormula (B) described herein are from about 0.03 to 2.5 mg/kg per bodyweight. An indicated daily dosage in the larger mammal, including, butnot limited to, humans, is in the range from about 0.5 mg to about 100mg, conveniently administered in divided doses, including, but notlimited to, up to four times a day or in retard form. Suitable unitdosage forms for oral administration comprise from about 1 to 50 mgactive ingredient. The foregoing ranges are merely suggestive, as thenumber of variables in regard to an individual treatment regime islarge, and considerable excursions from these recommended values are notuncommon. Such dosages may be altered depending on a number ofvariables, not limited to the activity of the compound used, the diseaseor condition to be treated, the mode of administration, the requirementsof the individual subject, the severity of the disease or conditionbeing treated, and the judgment of the practitioner.

Toxicity and therapeutic efficacy of such therapeutic regimens can bedetermined by standard pharmaceutical procedures in cell cultures orexperimental animals, including, but not limited to, for determining theLD₅₀ (the dose lethal to 50% of the population) and the ED₅₀ (the dosetherapeutically effective in 50% of the population). The dose ratiobetween the toxic and therapeutic effects is the therapeutic index andit can be expressed as the ratio between LD₅₀ and ED₅₀. Compoundsexhibiting high therapeutic indices are preferred. The data obtainedfrom cell culture assays and animal studies can be used in formulating arange of dosage for use in human. The dosage of such compounds liespreferably within a range of circulating concentrations that include theED₅₀ with minimal toxicity. The dosage may vary within this rangedepending upon the dosage form employed and the route of administrationutilized.
